Graphic card compatibility

Paracelso · ‎09-26-2024

I have recently buyed an used , refurbished PC , model : HP Prodesk 600 G2 MT.

It is equipped with a Intel DQ 670 W motherboard.

MB declared characteristics for PCIe graphic cards i.e. PCIe 2° 16X.

I have two cardS : AMD ATI Radeon HD 7450 , and ATI radeon HD 2400XT , as for the characteristics both should be compatibles , I am sure they work properly because were perfectly working when I demount from my old PC.

It happen that when I mount on PCIe slot the PC doesn't boot at all.

The display remain black , The leds of the LAN connector blinking , the fan rotating but that's all.

I have checked any characteristics on web and looking fo suggestion or similar problems occourred but no way to find any .

Could be a problem of BIOS update?

Is there someone able to give me an help?

Many thanks in advance.

To troubleshoot your HP ProDesk 600 G2 MT not booting with the PCIe graphics cards, start by checking for a BIOS update for compatibility. Ensure the graphics card is properly seated in the PCIe slot and verify that your power supply meets its requirements. Boot using integrated graphics and check the BIOS settings for primary display options. Test each graphics card individually to determine if one works. If issues persist, it may be a compatibility problem with the motherboard or the cards themselves.

Hey! Yeah, I’ve seen this happen before. Even though your Radeon HD 7450 and 2400XT should work, older cards sometimes just don’t play nice with newer HP boards.

A few things you can try: update the BIOS to the latest version that often fixes recognition issues. Also, try clearing the CMOS and make sure the cards are seated properly. Sometimes removing the onboard video in BIOS helps too.

If it still doesn’t boot, it might just be a compatibility thing with really old GPUs. Honestly, trying a slightly newer card that’s known to work with that motherboard usually saves a lot of headache.
